Major Description
Now that we have hadoop-client package in place it would make sense to migrate the client side dependencies to it. The only caveat here is that currently, only Oozie can take full advantage of the hadoop-client package since it manages its own classpath (or more precise Tomcat manages a classpath for it). All the other components (pig,hive,mahout,sqoop,hbase) use hadoop launcher script and thus can't be easily migrated to the classpath that is provided by hadoop-client.
Still this will simplify package dependency management and will allow us to gradually educate hadoop launcher scripts on the benefits of the client package.
